We are? I was under the impression that this had stopped, and that we now only do so indirectly in ways that are difficult to track (e.g. India importing raw materials from Russia, refining and shipping it to Europe).
Fully agree with your analysis that most of this is about Trumps ego and an attempt at asserting power.
Well, getting US out of Europe is probably a good thing in the long run. In the short run, maybe not so sure. That's a lot of troops to replace.
